This week, we will be handing out 25 App Store promo codes for TriDefense to celebrate this significant milestone in mobile gaming. If you’ve played the free version [iTunes link], you’ll definitely want to get your hands on the full version.

Tridefense is not your regular, run-of-the-mill tower defence game. Its high quality graphics, 3D positional audio, exceptional gameplay makes it one of the best strategy games on the iPhone and iPod Touch platform. And gamers have noticed it too — the game has been downloaded over 200,000 times in the last 12 months.

Despite the challenge, TriDefense is still a pleasure to play. It’s beautiful graphics and sensational soundtrack makes every gaming minute a pleasure.

You may also be interested to know that TriDefense 2 is in the works. Ciro Mondueri from TriDefense mentioned:

We’ve been hard at work with TriDefense 2, initially for iPad and iPhone 4.

To take advantage of the beautiful displays, all the graphics are being redone from scratch, in high resolution, with lots of detail and texturing. Even though we’re trying to keep the core mechanics of TriDefense, the mission structure, and how the waves of enemies are generated, will be completely different.

I hope you’re as excited as I am to get my hands on TriDefense 2. But for now, why don’t you get your hands on a free copy of TriDefense?
